Effect of polymer-surfactant association on colloidal force.
TL;DR: The experimental observations suggest that the associative polymers can be potential candidates for making the emulsions stable for a sufficiently long period, where the charges on the chain repel each other and the electrostatic repulsion collectively leads to chain stretching.

Magnetic hysteresis properties, Mössbauer spectra and structural data of spherical 250 nm particles of solid solutions Fe3O4–γ-Fe2O3
E. Schmidbauer,M. Keller +1 more
TL;DR: In this paper, the experimental results point to single domain particles with nonhomogeneous magnetization mode or to a magnetization medium intermediate between single domain and two domain particles in the spinel system, and the experimental data were found to disagree with the cation distribution according to a formula used in the literature for Mossbauer analysis.

Characterization of solutionizing behavior in VT14 titanium alloy using ultrasonic velocity and attenuation measurements
TL;DR: In this paper, the authors have shown that ultrasonic velocity can be used to identify the β-transus temperature in this alloy, and a new parameter, ratio of normalized differential of ultrasonic attenuation to normalized differential (RNDAV) has been used, which is found to increase monotonously with SAT and hence enabling unambiguous characterization of SAT.
